Abstract
The invention relates to a dotted heating device for blown film molds, and the device comprises a mold core, wherein a mold sleeve at the periphery of the mold core is uniformly provided with a plurality of adjustable heaters in a circular array mode and equipped with a temperature control instrument, and the outside of each adjustable heater is provided with a heat-insulating mat. The dotted heating device for the blown film molds provided by the invention has the beneficial effects that compared with an original one-surface heating mode, the device carries out heating by using a mold multi-dot heating structure, so that the temperature of a thick channel part can be increased, and the film at the thick channel part is affected by the relatively high temperature, thereby improving the liquidity and eliminating the thick channel of the film; and the dotted heating device is beneficial to the temperature adjustment of the heaters and can control the heaters, thereby ensuring the quality of a blown film.
Description
Technical field
The present invention relates to the inflation film mechanical field, relate in particular to a kind of inflation film mould point type heater.
Background technology
Blowing generally is to make the hot melt preform blowup that closes in the mould form the method for hollow product by means of gas pressure, also is plastic working method commonly used.Blow mold is compared with injection mo(u)lding, and equipment manufacturing cost is lower, and adaptability is stronger, good, the plastic goods with complicated fluctuating curve of plastic performance.Existing inflation film die orifice place generally only possesses one group of mode of heating, and there is one group of heater heating the die orifice position and receives temperature control instrument control to be set to unified heating-up temperature; But because one group of heater can only be set a kind of temperature, therefore make inflation film can't avoid producing " honest and kind ", promptly a place or several places thickness exceed preassigned, thereby influence film quality; Therefore, adopt the standard of " honest and kind must not more than two " to come standard, existing plastic uptake film apparatus can't solve the honest and kind problem of film.
Summary of the invention
To above defective, the present invention provides a kind of inflation film mould point type heater, through some groups of heaters being set and being furnished with the control of corresponding temperature control instrument, thereby reach thickness evenly, help realizing adjustment, lower-cost purpose.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
A kind of inflation film mould point type heater comprises core rod, and the circular array formula evenly is provided with some variable heater and is furnished with temperature controller on the die sleeve of said core rod periphery, and each variable heater outside is provided with a heat insulating mattress.
The beneficial effect of inflation film mould point type heater of the present invention is: the mode of heating of comparing an original face; This device adopts mould to organize a heating arrangement heating more; Can improve temperature with honest and kind place occurring; Make the film at this honest and kind place receive higher relatively temperature effect, improved flowability, it is honest and kind to have eliminated film; Help heater and regulate temperature, and control, guaranteed the quality of inflation film.
Description of drawings
According to accompanying drawing the present invention is done further explain below.
Fig. 1 is the apparatus structure sketch map of the said inflation film mould of embodiment of the invention point type heater;
Fig. 2 is the heater structural representation that existing inflation film mould adopts one group of heater;
Fig. 3 is the heater vertical view that existing inflation film mould adopts one group of heater;
Fig. 4 is another structural representation of the said inflation film mould of embodiment of the invention point type heater.
Among the figure:
1, constent temperature heater; 2, die sleeve; 3, core rod; 4, heat insulating mattress; 5, variable heater.
The specific embodiment
Shown in Fig. 1-4; The described inflation film mould of embodiment of the invention point type heater; Comprise core rod 3, on the die sleeve 2 of said core rod 3 peripheries some variable heater 5 are set evenly, these variable heater 5 circular array formulas are arranged also is furnished with corresponding temperature control instrument and controls; In producing thin-film process, can suitably adjust temperature when " honest and kind " part occurring; Each variable heater 5 outside is provided with a heat insulating mattress 4; Compare the only mode of heating of a face of original employing constent temperature heater 1; This device employing mould is organized a heating arrangement more to be heated, and can improve temperature with honest and kind place occurring, make the film at this honest and kind place receive higher relatively temperature effect; Improved flowability, it is honest and kind to have eliminated film.Also can between two adjacent variable heater 5 of position, heat insulating mattress 4 be set.
Claims (2)
1. an inflation film mould point type heater comprises core rod (3), it is characterized in that: the peripheral die sleeve (2) of said core rod (3) is gone up the circular array formula and some variable heater (5) evenly is set and is furnished with temperature controller.
2. inflation film mould point type heater according to claim 1 is characterized in that: each variable heater (5) outside is provided with a heat insulating mattress (4).
